Honeywell electronic air filters are a great way to keep your home's air clean and free of dust and other particles. Depending on the amount of use, these filters should be removed and replaced every 6 to 12 months. Honeywell recommends replacing the filter every 6 months or one year depending on use. To test if your Honeywell electronic air purifier is working properly, run the oven fan and then tap the return duct (cold in winter) with the palm of your hand several times.
This will release some dirt in the ducts, which will enter the air filter and cause it to make clicking noises. This indicates that it is working correctly. However, studies have shown that continuous use of an electrostatic air filter for household ducts can raise ozone concentrations to six times higher than outdoor ozone levels. This means that electrostatic precipitators may not be able to filter all particles with the same level of efficiency, depending on their size.
Electrostatic air purifiers promise to remove dust and other particles from the air using an electromagnetism trick. But there are serious doubts about their effectiveness and whether they could actually emit more harmful pollutants than they remove from the air. An electrostatic air filter is a washable filter that traps dust and other particles to keep the air clean. However, it is not recommended to use this type of air purifier due to the high levels of ozone it can generate.
A common air purifier used to control particle levels in the air is an electrostatic air filter unit, which generates electric fields to trap particles (referred to as an electrostatic precipitator in industrial terms). Once each particle is charged, the Honeywell air purifier will use oppositely charged plates to attract these particles and clean them from the air. Electrostatic air filters are one of many options available for improving indoor air quality, but it's important to understand their limitations before making a purchase. Generally, an electrostatic filter is not rated higher than 5 or 6, while other high-efficiency filters have ratings between 10 and 16 and even higher.
Depending on your budget and your particular allergies, a HEPA filter or Molekule device may be a better option for reducing allergen levels in the air. This is a reference to the filter medium and is independent of the category of electronic air filters that use an external power supply.
